Abstract
Vorgeschlagen ist ein hebelartiger Nockenfolger (4) eines Ventiltriebs (1) einer Brennkraftmaschine (2). Der Nockenfolger soll durch eine ausgewählte Merkmalskombination die Schaftendenfläche (16) eines Tellerhubventils (17) exzentrisch kontaktieren, um das Tellerhubventil gezielt zur Rotation anzuregen. Proposed is a lever-like cam follower (4) of a valve train (1) of an internal combustion engine (2). By means of a selected combination of features, the cam follower is intended to eccentrically contact the shaft end surface (16) of a plate-lifting valve (17) in order to purposefully stimulate the disk-lifting valve to rotate.
